Thread: ceramic lined gate valve for abrasive application

  1. ceramic lined gate valve for abrasive application

    Structural ceramics are used on the valve gate and seat to resist wear, corrosion, high temperatures and thermal shock.
     Product is suitable for conveying wearing media, including dust and particles in vacuum systems.
     Dual seats create bi-directional sealing.
     Required operating power is low; manual, electric and pneumatic actuators may be used.
     Materials are selected on an application basis. Options include Super Duplex Stainless Steel, Hastelloy, Stainless Steel, Cast Steel, and others, as required.
     Multiple ANSI and DIN flange standards are available. Higher classes available.
     Typically used for on/off service
     Ceramic seat materials are also selected on an application basis. Options include high alumina ceramics, silicon carbide, and others.
    Used in these industries:
     Power Plant Bottom Ash
     Bottom ash pyrite systems
     FGD Slurry Systems
     Conveying Systems for dust, powder and slurry in mining and aluminum production

    Features:

    Product type

    The Ceramic Double Disc Gate Valve is ceramics-to-ceramics sealing, also named as parallel double disc valve, or ceramic double disc valve or ceramic double gate valve.

    The standard end connection of ceramic double disc valves is flanged type, but if the installation space is limited, wafer type is available.

    Three piece bodies of Ceramic Double Disc Gate Valves are very easy for assemble and reliable for maintenance.

    Self-cleaning disc design allows disc to move freely and avoid being scratched by solid particles.



    Temperature range

    Usually working temperature of pneumatic conveying system is not so high, but under some conditions like economizer valves in coal fired power plant, the working temperature may be up to 450 ℃. Then special design of ceramics and packing material will be considered.

    Detailed information about working temperature of our Ceramic Double Disc Valves, please contact us at sales@ceramic-valves.com.

    Normal working temperature of Ceramic Double Disc Valves: -29 °C ~ +200 °C

    High temperature design of Ceramic Double Disc Gate Valves: -29 °C ~ +450 °C



    Valve tightness

    The tightness of valve is very important. FUVALVE has advanced ceramic processing technology and skilled technicians. All ceramic sealing faces of the Ceramic Double Disc Gate Valves are well ground and polished, which ensure Class V leakage as per FCI 70-2.

    Other tightness rates upon request.

    FUVALVE Ceramic Double Disc Gate Valves have much longer service life than the other similar products.



    Design standards

    Valve body ASME B16.34

    Face-to-Face: Manufacturer’s Standard, customized length of Ceramic Double Disc Valves is available.

    Valve Testing: API 598

    The structure of FUVALVE Ceramic Double Disc Gate Valve is as the following exploded drawing.

    Typical Applications:

    In many bulk material handling systems, such as coal fired power plant, steel plant, cereals transport system, cement transport systems, etc., generally in these applications, pneumatic conveying method is used to reduce manpower demand, and improve system efficiency and reliability. But abrasion of valves is a big problem that causes customers a lot trouble.

    The valve sealing surface and flow path of these valves are destroyed seriously by high speed solid materials. FUVALVE develops Ceramic Double Disc Valves for these applications which works quite well for coal fired power plants all over the world.


    Ceramic Double Disc Valves are suitable for any bulk materials handling system including the mediums listed as below: Silicon Powder,Alumina Powder,Coal Powder,Cement,Lime Stone Powder,Magnesium Powder,Quartz Sand,Metallurgical dust,Ores,Fly Ash,Granules.
